6. Heating mode operation
• Operating frequency of compressor depend on the difference of the temperature
(= compressor off temp. - intake air temp.)
• Compressor off temp. = setting temp.+3.0°C
on temp. = setting temp.
• If compressor operates at some operation frequency, the operating frequency of compressor cannot be
changed within 30 seconds.
• Condition of compressor turned off
- When intake air temperature r3°C above the setting temperature.
• Condition of indoor fan turned off
- While in compressor on:indoor pipe temp. < 26°C
off: indoor pipe temp. < 37°C
• While in defrost control, between the indoor and outdoor fans are turned off.
• Compressor 2minutes delay
- After compressor off, the compressor can restart minimum 2 minutes later.
